This set of three-dimensional human organ replicas supports the study of the human body in the Upper Elementary and, selectively, Upper Elementary extension work, giving children accurate, tactile references for the heart, lungs, brain, and other major organs. Unlike flat nomenclature cards alone, these objects anchor classification and research work in something children can hold, compare, and examine from all angles. They pair naturally with your three-part cards and research booklets for a richer, more concrete entry point into biology.
